Abstract

The manufacture of bioplastics from potato starch (Solanum tuberosum L.) and glycerol from leech oil with the addition of TiO2 has been done by varying the concentration of TiO2. This study aims to study the effect of the addition of TiO2 on the physical, mechanical properties and bioplastic biodegradation rate of cassava starch and glycerol from leech oil. The research was conducted by making glycerol from used cooking oil, making bioplastic films with various concentrations of TiO2 0; 1; 2; 3 and 4%, characterization of bioplastics which includes physical, mechanical and chemical properties as well as biodegradation tests using the soil burial test method. The addition of TiO2 as a bioplastic filler can affect the physical, mechanical properties and the rate of biodegradation in the soil. The results showed that each addition of 1% TiO2 increased the thickness by 22,966 microns, increased the tensile strength value of 0.0853 N/mm2, decreased elongation by 5.0987%, and increases the average Young's modulus by 0.0599 MPa. The best bioplastic mechanical test results were produced at a starch composition of 2.5 grams and 2% (w/v) of TiO2 particles. The addition of TiO2 did not have a significant noticeable difference to the rate of biodegradation. However, it has a close correlation between the loss of bioplastic mass and the length of burial.
